Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Ladies 38mm Stainless Steel Diamonds Grey Dial Diamond Set Index Steel Bracelet 220.15.38.20.57.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of Omega's most celebrated modern collections, bridging the gap between a serious Swiss sport watch and an elegantly dressed daily companion. Introduced as a versatile, water-resistant timepiece inspired by the sea and suitable for life on land, the Aqua Terra line has earned a devoted global following thanks to its clean horizontal "teak" or open dial motifs, polished and brushed case finishing, and robust movement technology. Reference 220.15.38.20.57.001 represents a pinnacle expression of this lineage, presented in a 38mm format that wears beautifully on a wide range of wrists.

The case of this reference is crafted in polished and brushed stainless steel measuring 38mm in diameter — a size that sits squarely in the sweet spot for contemporary watch wearing, neither oversized nor petite. The stainless steel bracelet integrates fluidly with the case, offering a unified, sophisticated look that transitions effortlessly from boardroom to weekend. Every surface reflects Omega's meticulous attention to finishing, with alternating brushed and polished links adding depth and texture.

What immediately distinguishes ref. 220.15.38.20.57.001 is its lavish use of diamonds. The bezel is set with brilliant-cut diamonds that encircle the case in a continuous band of light, while the grey dial features diamond-set indexes in place of standard hour markers. The result is a dial that captures and refracts light dramatically at every angle, lending the watch an undeniable presence. The grey dial color provides a sophisticated, contemporary backdrop that allows the diamond indexes to truly shine without veering into overt flamboyance.

At the heart of this timepiece beats Omega's Co-Axial Master Chronometer movement, a technology certified by METAS — the Swiss Federal Institute of Metrology — to meet the most stringent accuracy, anti-magnetic, and performance standards in the Swiss watch industry. The Co-Axial escapement reduces friction compared to a traditional lever escapement, resulting in longer service intervals and sustained precision over the life of the watch. Master Chronometer certification means this movement has passed eight tests and is confirmed to perform to within 0 to +5 seconds per day — a standard that surpasses traditional COSC chronometer certification.
